PROCESS FOR FUNCTIONALIZING A GLASS REINFORCEMENT FOR COMPOSITE MATERIAL - (EN) Process for surface functionalization of a glass reinforcement, characterized in that the said reinforcements are chemically modified by means of surface treatment by the action of a homogeneous plasma at atmospheric or sub-atmospheric pressure in a controlled, oxidizing or nitriding gas atmosphere, and in that the said surface portion is contacted with an aqueous impregnating solution of an organic or inorganic matrix, or directly with the matrix.

GLASS YARNS CAPABLE OF REINFORCING ORGANIC AND/OR INORGANIC MATERIALS - The invention relates to a glass yarn capable of being obtained by a method consisting of mechanically drawing molten glass threads flowing from orifices disposed at the base of a die, of which the chemical composition is substantially free from boron oxide and comprises the following constituents within the limits defined hereinafter expressed in percentages by weight:

GLASS FIBER STRUCTURE DESIGNED TO REINFORCE BONDED ABRASIVE ARTICLES - The invention relates to a structure based on glass fiber coated with a resin composition designed to reinforce bonded abrasive articles, the resin composition being characterized in that it comprises the following constituents in the proportions indicated, expressed in percentage by weight of solid matter:

GLASS MELTING IN THE PRESENCE OF SULPHUR - The invention relates to a process for manufacturing a glass by melting, at more than 1300° C., batch materials comprising silica and an alkali or alkaline-earth metal sulfate, characterized in that a sulfide is added to the batch materials in order to reduce the height of foam at the surface of the bath of liquid glass at more than 1300° C. The invention reduces the formation of foam at the surface of the glass and improves the heat exchanges between the overhead burners and the glass bath. The invention is particularly suitable for glass intended to be fiberized.

Reinforcing Yarns and Composites with an Improved Fire-Resistance - The present invention relates to a composition for reinforcing strands, characterized in that it includes at least one additive capable of acting at the strands/matrix interface so as to improve the fire resistance of the strands/matrix composite, and it also relates to the strands and composites obtained.
